INTRODUCTION Please read this manual carefully before operating the unit. Pay particular attention to the instructions for use accompanied by the writing “DANGER” or “CAUTION”, as failure to comply with these instructions could cause damage to the appliance or property and injury to persons. For any malfunctioning not contemplated in this guide, immediately contact an authorised after-sales service centre. 1. Do not store or unpack the unit in a wet area or expose to rain or water, it may cause the unit short circuit and may result electric shocks or fire. 2. Do not install in a place where flammable gas may leak, it may cause fire. 3. This unit is designed for domestic and commercial use only, if used in certain enviroments, such as manufacturing workplace, the air conditioner may not function efficiently The manufacturer cannot be held liable for any damage or injury caused by misuse of the appliance or by partial or superficial knowledge of the information contained in this guide.
LOCATION FOR FAN COIL UNIT Select the location of fan coil unit with following consideration: 1. The front of air inlet and outlet shall be free from any obstruction. The outlet air should flow out freely. 2. The wall where unit is to be mounted should be strong enough to bear the weight and not to produce noise. 3. Ensure the clearance on every side of fan coil unit (see drawing below). Avoid installing the unit in direct sunlight.
RECOMMENDATIONS - Installations must be performed by a qualified technician. - Before carrying out installation, put proper individual protection device. - This air conditioner must be properly installed in accordance with the Installation Manual. - Check all local codes and ordinances that could affect installation of this unit. - Refer to rating plate on each unit for the correct voltage, frequency and current. - Be sure that the power supply corresponds to the specified rating in the nameplate. - Do not use the extension cables. In the case extended cables are needed use terminal block. - Refer to dimensional drawings for location of refrigerant tubing, condensate drain, and electrical connections before setting in place. - The appliance shall be installed in accordance with national wiring regulations.

6. Drill a piping hole 70.0 mm diameter hole either from the right or to the left fan coil side and make sure that the hole is slightly slant downward. 7. If the wall is hollow please provide a sleeve for tube assembly to protect the drain line, pipings and field connection.
MOUNTING PLATE INSTALLATION 1. After a suitable place for installation has been selected, place the mounting plate horizontally on the wall. If the unit is not perfectly installed horizontally, some problems with condensate discharge may occur. 2. Referring to the figure below, mark the location for the wall plugs and the hole for the pipings.

MAINTENANCE If you plan to idle the unit for a long time, performed the following: 1. Operate the fan motor to dry off the unit. 2. Stop the air conditioner and disconnect power. 3. Remove the batteries from the remote controller. CHECK BEFORE OPERATION 1. Check the wiring if is not broken off or disconnected. 2. Check the air filter if is installed and the air outlet is not blocked. PULIZIA DEL VENTILCONVETTORE 1. Pulire la parte esterna ogni settimana, con un panno asciutto bagnato con acqua e detergente delicato, evitare l’uso di altri detergenti. 2. Il telaio con griglia con il pannello può essere rimosso, pulirlo con acqua tiepida non superiore ai 40°C e asciugare con un panno asciutto. 3. Non usare un panno trattato chimicamente o uno spolverino per pulire l’unità. 4. Non usare benzene, solventi, lucidanti chimici o simili solventi per pulire. Possono scolorire, screpolare o deformare la superficie plastica. CLEANING AIR FILTERS Dirty and clogged filters reduce the cooling efficiency of the unit, it is recommended to clean the filters once every 2 weeks or weekly. 1. Open the deco panel by grasping the rounded groove and pulling it towards you. 2. Hold the tabs of air filter and raise it slightly, then pull it downwards. 3. Clean the air filters with vacuum cleaner or wash it with water then dry it up in the cool place. 4. Do not use benzene, thinner, polishing chemical or similar solvents for cleaning.

PROBLEM 1. Air conditioner doesn’t operate at all. PROBLEM CAUSE 1. Is the power been shut down or power failure? 2. Is the wiring connection loose? 3. Is the power leakage protection in operation? 4. Is Fuse blown or Circuit breaker open? REMEDY 1. Wait for power resume. 2. Tighten the connection. 3. Reset the power leakage protection. 4. Replace fuse or reset the circuit breaker.
MALFUNCTIONING - In the case of malfunctioning remove the power to the unit then repower it and start up the unit again. If the problems occur again, call services personnel promptly. - Air conditioner must be operated comply with the Power, Amps and Hz noted in the unit name plate. Failing to do so, it may cause permanents damage to the unit. - The ground must be connected. Do not connect the ground wire to water pipes, gas pipes, lighting rods, and telephone ground wire. - Select the most appropriate temperature to provide maximum comfort in room.

During operation always leave the filters on the unit otherwise the dust in the air could soil the surface of the evaporator coil. - The air direction can be adjusted appropriately. The air coming out of the unit must not strike people directly it could cause cold sensation and resulting discomfort. Adjust the air deflector by hands and use the remote control to adjust the horizontal louver. Do not put anything in the air inlets or outlet slot. this could cause injury to the people and damage to the fan. Splashing water on the air conditioner can cause an electrical shock and malfunction on the unit.

PROBLEMS THAT NEEDS QUALIFIED PERSONNEL ASSISTANCE. PROBLEM 1. Air conditioner doesn’t run. PROBLEM CAUSE 1. Faulty contactor, relay and fan motor capacitor. 2. Control board not functioning. 3. Terminal loose. REMEDY 1. Replace faulty components. 2. Check the cause of malfunctioning and replace control board, if necessary. 3. Check and retighten. PROBLEM 1. E1 blinking 2. E2 blinking 3. E3 blinking PROBLEM CAUSE 1. Room Sensor error is activated. 2. Freeze Sensor error is activated. 3. Inlet water Sensor error is activated. REMEDY 1. Check all sensors for loss connection and replace defective sensors if necessary. PROBLEM 3. E4 blinking PROBLEM CAUSE 1. Inlet water temperature fault is activated because; - in cool mode the starting temperature is ≥20°C. - in heat mode the starting temperature is ≤35°C. REMEDY 1. Check the inlet water temperature whether right to start in cool/heat mode. - in cool mode the inlet water temperature is ≤15°C. - in heat mode the inlet water temperature is ≥ 40°C.
